Europa has a thick ice shell surrounding an ocean of water, and astrobiologists are hoping there's life down there. Getting through the ice will be a monumental engineering challenge, but the chemicals from life could make their way to the surface of Europa. In a new paper, scientists proposed using an ultraviolet laser which causes amino acids to fluoresce. If those molecules are seen at the surface, they could be a biosignature for life down in the ocean.
